Description

Technical Field

[0001] This utility model belongs to the field of machining, and specifically relates to a quick clamping fixture for a casting shock absorber tower. Background Technology

[0002] In existing machining processes, traditional techniques typically require multiple clamping and positioning of castings, often necessitating the use of specialized fixtures. For casting damping towers with complex shapes and irregular structures, traditional tooling struggles to achieve rapid and accurate positioning and clamping. This not only consumes significant time and manpower for fixture adjustments and workpiece fixation but also easily leads to decreased machining accuracy due to inaccurate clamping.

[0003] Meanwhile, traditional tooling lacks stability during processing and is prone to loosening or deformation, which further affects processing stability and product quality. In addition, the design and manufacturing costs of special fixtures are high, and each time the workpiece is changed, the fixture needs to be readjusted, which not only increases production costs but also reduces production efficiency.

[0004] Therefore, when dealing with complex workpieces such as cast vibration damping towers, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a quick clamping fixture for casting shock absorber towers. Through the combined use of several pressing heads, positioning parts and adjustable support screws, contour clamping is achieved; at the same time, the adjustable support screws can flexibly adjust the height, thereby fitting the product, supporting and absorbing shock, and significantly improving clamping efficiency and processing stability.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a quick clamping fixture for a casting vibration damping tower, including a base, several positioning support columns, and several supporting support columns. The positioning support columns and supporting support columns are spaced apart and stand on the base. Each positioning support column and supporting support column is equipped with a quick-pressing plate assembly at its top. The positioning support columns and supporting support columns are stepped, with positioning elements and adjustable support screws respectively located on the middle steps. An elastic support column is also provided in the middle of the base. The spaced positioning support columns and supporting support columns form multiple support points, providing stable support for the workpiece. The positioning elements on the positioning support columns can initially position the workpiece, ensuring it is in the correct position during clamping, thereby improving machining accuracy. The adjustable support screws on the supporting support columns can be height-adjusted according to the shape and size of the workpiece, achieving flexible clamping. The elastic support column in the middle of the base provides additional elastic support, further enhancing the stability of the workpiece.

[0007] Furthermore, the quick-release platen assembly includes a mounting base, a platen, a pressure rod, a transmission rod, and a lower pressure head. The mounting base is located on top of the positioning support column and the supporting support column. The platen is mounted on the mounting base via the transmission rod. The tail end of the pressure rod is connected to both the mounting base and the platen. The lower pressure head is located at the head end of the pressure rod. Through the linkage mechanism of the platen and the pressure rod, the quick-release platen assembly enables rapid clamping and release. Operators can fix or release workpieces simply by pressing or lifting the platen, greatly shortening clamping time and improving production efficiency.

[0008] Furthermore, the pressing heads of the plurality of rapid pressing plate assemblies are all oriented towards the center of the base; the steps of the positioning support column and the supporting support column are all oriented towards the center of the base. The fact that the pressing heads, positioning support columns, and supporting support columns are all oriented towards the center of the base concentrates the clamping force on the workpiece in the central area of ​​the workpiece, making the force on the workpiece more uniform during processing.

[0009] Furthermore, the pressure head, positioning component, and adjustable support screw work together to achieve contour clamping. During processing, if it is necessary to switch to workpieces of different sizes, the operator only needs to adjust the height of the adjustable support screw and the pressure of the pressure head to quickly complete the clamping and adjustment of the workpiece, without the need to redesign and manufacture the fixture, thereby improving the adaptability and flexibility of the tooling.

[0010] Furthermore, the adjustable support screw is connected to the supporting column via a thread. This threaded connection allows the adjustable support screw to move along the supporting column, thus enabling flexible height adjustment.

[0011] Furthermore, at least one of the adjustable support screws is tilted. The tilted adjustable support screw better conforms to the product's placement surface, ensuring the successful contour clamping.

[0012] Furthermore, at least one of the positioning components is provided with a limiting block at its top. The limiting block is used to confirm whether the product is accurately positioned by the positioning component. If the limiting block cannot fit the product, the clamping angle of the adjustable support screw and the pressing head needs to be adjusted.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] 1. This utility model provides a quick clamping fixture for a casting shock absorber tower, which achieves contour clamping through the combined use of several pressing heads, positioning parts and adjustable support screws;

[0015] 2. This utility model provides a quick clamping fixture for a casting shock absorber tower. The adjustable support screw can flexibly adjust the height, thereby fitting the product, supporting and absorbing shock, and significantly improving clamping efficiency and processing stability.

[0016] 3. This utility model provides a quick clamping fixture for a casting shock absorber tower. During the processing, if it is necessary to switch between workpieces of different sizes, the operator only needs to adjust the height of the adjustable support screw and the pressure of the lower pressure head to quickly complete the clamping and adjustment of the workpiece. There is no need to redesign and manufacture the fixture, which greatly improves the adaptability and flexibility of the fixture. Attached Figure Description

[0043] This utility model discloses a quick clamping fixture for a casting vibration damping tower. The adjustable support screw 31 is screwed down; the pressure plate 42 is pressed, causing the lower pressure head 45 to rise; the product is placed in the fixture and positioned by the positioning component 21, with the limiting block 211 confirming accurate placement, while the elastic support column 11 provides elastic support to the product; the pressure plate 42 is raised, causing the lower pressure head 45 to descend and fall onto the upper surface of the product; the adjustable support screw 31 is adjusted upwards to ensure it fits snugly against the product, completing the clamping process.

[0044] The above description is only a preferred embodiment of the present utility model.
